Trigger 6 routes the External Trigger signal from the M9301A to the M9311A.
In this example, the M9301A has been installed in Slot 8 (Bus Segment 2),
while the M9311A is in Slots 5 (Bus Segment 1). Therefore, backplane trigger
6 must be redirected from Bus Segment 2 to Bus Segment 1. Use the drop-
down menu to select "1 ← 2".
Trigger 7 routes the ALC Trigger signal from the M9311A to the M9310A.
Since the M9311A is now in Bus Segment 1 and the M9310A is in Bus
Segment 2, backplane trigger 7 must be redirected from Bus Segment 1 to
Bus Segment 2. Use the drop-down menu to select "1 → 2".
If two to four sources are installed in the M9018A chassis, each source should
have its own backplane trigger line. If you have a source that spans segment 1
and segment 2 and another source that spans segment 2 and segment 3, using
a single set of trigger lines with 1 → 2 → 3 and 1 ← 2 ← 3 does not work for
both sources. In this case, you must configure one set of trigger lines with 1 →
2 and 1 ← 2 connections and another set of trigger lines with 2 → 3 and 2 ← 3
connections.
Configuring PXIe Backplane Triggers for Multi-Channel Operations
For a multi-channel system spanning one or more chassis, you must configure
additional backplane triggers for the required synchronization between the
channels in a chassis.
On each master channel, configure the PXI backplane trigger line from the
master channel to all the slave channels.
On each slave channel, configure a unique PXI backplane trigger line as the
handshaking line from the slave channel to the master channel.
Recommended Module and Backplane Layout for M9381A VSG
The following is the recommended module and backplane layout for multiple
M9381A PXIe VSGs in two chassis. The diagram below shows the layout of the
second chassis. Each chassis is configured in the same manner.
